Re: Classic Petrol Tap

Thank you Richard for the interesting info concerning the lever plate, restricting the tap to only 'on' or 'reserve', both controlled by the vacuum fuel valve. I have only once run out of petrol when in the IoM, coasted to the side of the road, less than 5 mins to switch to reserve and away again, I...

Re: Classic Petrol Tap

John/Geoff,

I hope I am not tempting fate but I have not experienced any issues with the fuel tap, either leaking or the issues of the carbs drying out

Perhaps I have just been lucky

Norton Rotary New Rear Chain Gaiters

Its thanks to Chris Harvey’s hard work that I now have two brand new rear chain gaiters. This means that I will be able to keep my Commander on the road for the foreseeable future, these bikes are not designed to be used without the gaiters as they provide an oil bath and subsequently the lubricatio...

Re: Good evening

The oil must be low ash, I use Castrol Tection DD40, Shell Rotella 40 is recommended, some Rotary owners use a Silkolene oil

I suspect if Morris straight 40 Golden Film was used it would carbon up very quickly

Funny little ways

This may be of interest to some Commander owners.

David,

I agree, however I feel the Boyer gives a more even tick over, I have been told that the Boyer and Mini Mag use a different retard setting, that said the Mini Mag is good system.

All I have to do now is save up for a new one to carry as a spare.
